ICE-CREAM FREEZER.

SPECIFICATION forming part of Letters Patent No. 243,336, dated June 21,1881.

Application filedApril25, 1881. (No model.)

To all whom it may concern Be it known that I, ISAAC S. WILLIAMS, acitizen of the United States, and a resident of Philadelphia,Pennsylvania, have invented certain Improvements in Ice-Oream Freezers,of which the following is a specification.

My invention relates to an improvement in that class of ice-creamfreezers in which a cylindrical can containing the cream is vibrated inan ice-receptacle by the hands applied to a handle on the lid of thecan, and the object of my invention is to furnish the can and lid with asubstantial and permanent retaining device for preventing one fromturning independentl y of the other.

In the'accompanying drawings, Figure 1 is a perspective view of theupper portion of acream-can and the lid, showing my improvement; andFig. 2, a sectional plan of the lid.

As cream-cans of the class of ice-cream freezers to which my inventionrelates must be vibrated in the ice-receptacle by means ota handle onthe lid, it is essential that provision should be made for preventingthe turning of the said lid on the body of the can.

The devices heretofore used for this purpose have been of a very flimsycharacter, as they were generally composed of bent wires, one solderedto the side of the can at the upper end of the same, and the other tothe flange of the lid, which is necessarily recessed or notched andweakened; and no proper provision was made for re-enforcing thisweakened part of the flange.

In order to obviate this defect I secure to i the flange m of the lid Aa casting, B, preferably of malleable iron, which is recessed at a frombelow, the said recess coinciding with that in the flange, the castingbeing preferabl y galvanized or tinned and secured by solder.

The body D of the can is surrounded near its upper edge by a rim, 1), onwhich the lid, when in place, rests, and a solid block, Gr, of metal,secured to the body of the can, is fitted to this rim, and extendsupward therefrom, the block being of such dimensions that it will fitfreely in the recess a of the castingB, thereby preventing the lid fromturning on the can.

it is'necessary, in applying the casting to the lid, to cut through theflange of the same to the extent of the recess a; but the flange thusweakened is properly re-enforced by the casting B, which bridges thesaid recess in the flange, the rigidity of this casting thus serving tostrengthen the lid at the point where ordinary lids are necessarilyweak.

I claim as my invention- The combination, in a cream-can of an icecreamfreezer, of the recessed casting B, secured to the flange m of the lidwhere the latter is recessed, with the body D of the can, and its blockGr, fitted to the rim 1) of the can, all as set forth.

In testimony whereof I have signed my name to this specification in thepresence of
